I AIR REGISTER FOR FURNACES.

Application filed January 23, 1926. Serial'No. 83,395.

the premature discharge of the heated combustion products from thefurnace stack, allowing the same to be fully utilized. I

Another and equally important object of the invention is to provide anair register of the character mentioned wherein a novel operating meansis employed for collectively moving the Various air regulating vaneswhereby to control the supply of air to the furnace combustion chamber,insuring an even inflow of air about the complete structure and throughits various discharge ports.

Other objects of the invention will be in part obvious and-in partpointed out hereinafter.

in order that the invention and its mode of operation may be readilyunderstood by persons skilledin the art, I have in the accompanyingillustrative drawings, and in the detailed following description basedthereon, set out one possible embodiment of the invention.

In these drawings: V p I Figure 1 is a front elevation of the improvedregister, showing the same mounted in a furnace front, one portionof-the regis ter and the furnace front being broken and shown insection, V

Figure 2 is an enlarged vertical transverse section'taken on the line 22of Figure 1 looking in the direction in which the arrows point, and UFigure 3 is an enlarged fragmentary'detail, partly in section, showingthe mounting of the air regulating vanesadjacent their respective airdischarge ports and likewise, the manner in'which such vanes areselectively connectedto the operating ring. Having more particularreference to the drawings in connection with which like characters ofreference will designate corresponding parts throughout, the improvedair register may be stated to comprise an away annular casing of sheetmetal or other suitable material generally indicated in its entiretybythe numeral 1, said casing being provided with an annular airreceiving and distributing chamber 2 having an air intake port oropening 3 formed in the lower por tion .Of the inner side wall thereofwhile a plurality of equi-spaced air discharge ports 4: are formed inthe inner wall of the annular chamber 2 and are adapted to discharge airfrom the chamber into the combustion chamber of an equipped furnacewhereby to effect an intimate mixture of atomized oil and oxygentherewithin, thus perfecting combustion.

The casing 1 of the air register is adapted to be arranged in a furnacefront, such casing, as will be noted upon reference to Figure 1, havingthe lateral chamber like lntegr'al extremities 5 and 5 alsocommunieatingwith the annular chamber 2 of the air register, whereby preheated airwill pass thereinto from a point below the furnace '(the heating zone orair heating chamber described and claimedby me in a copending'application for United States Letters Patent'filed January 23, 1926,Serial Number 83,396) and will be fully and evenly distributed aboutsaid, annular chamber 2 for discharge from, such annular chamber by wayof the circularly arranged and spaced air discharge ports 4 directlyinto'the I furnace combustion chamber. v

'In 'ord'er that the various ports 4 may be adjusted so as toeffectually regulate the discharge of' air from the annular casing 2into the combustion chamber of an equippet furnace, a plurality of aircontrolling or regulating vanes generally indicated by the numeral 6 arepivotally mounted inthe opposite side walls of adjacent portions of thecasing 1 through the medium of pivot pins 7 certain of the ends ofwhichare ex tendedbeyond adjacent portions of their respective walls andprovided with substantially right angularly disposed extensions 8. Thefree extremities of these extensions'8 are loosely received betweenrelativelyspaced pins 9 securely mounted in. a pair of'juxtaposedoperating rings 10; the pins 9, obviously, serving as means for fixedlyinterconnecting said rings 10 and likewise, for effecting a means ofengagement as between such rings 10 and the right angularly extendedportions 8 of the aforesaid pivot pins 7 To permit the transmission ofrotary adjusting motion to the operating ring constituted by thejuxtaposed rings 10, a plurality of radially disposed bracing arms 11are fixedly connected to portions of one of said rings 10 in the mannershown in the Figures 1 and 3, one of said arms being provided with ahandle extension 12 whereby an operator of the device may readily engagethe same and impart a rotary or rocking adjusting movement thereto fordirecting pivotal movement to the various air regulating vanes 6 throughthe medium of their right angular extensions 8 from the pivot pins 7. Bythis means of adjustment through the handle 12, it will be fullyunderstood that the air regulating vanes 6 may be minutely andefiiciently adjusted with respect to their adjacent air discharge ports1 and by consequence, the discharge of an even and uniform flow of airfrom the annular chamber 2 through the said ports t into the comb-ustionchamber of an equipped furnace will be insured.

A concentrically arranged opening is formed in the outer side wall ofthe casing 1 and has a sleeve-like bracket 13 secured to the same asindicated at 14; a burner nozzle 15 being extended through thissleeve-like bracket 13 and opening into the combustion chamber of theequipped furnace, whereat, if desired, said nozzle may be supplied withthe usual shield 16.

In operation of my improved air register, the casing 1 with the integralextremities 5 and 5 is properly positioned adjacent the furnace fronthereinbefore mentioned and through said extremities and the opening 3,it will be understood that a continuous and even inflow of preheated airfrom the heating zone beneath the furnace and into the chamber 2 will beinsured. To regulate the discharge of this air circulating through theannular chamber 2 into the combustion chamber of an equipped furnace, itis only necessary that the operating handle 12 be rocked in the desireddirection, thereby effecting a collective pivotal movement of thevarious air regulating vanes 6 with respect to their particulardischarge ports 4 inasmuch as the right angular extensions 8 of thepivotpins 7 are loosely connected to the operating ring 10 in the mannerhereinbefore described. By proper regulation of the air regulating vanes6, it will be understood that an even and uniform supply of air from thevarious discharge ports 4- into the combustion chamber of an equippedfurnace may be successfully maintained. If desired, each of the airregulating vanes may have offset portions 17 formed upon their freeextremities, whereby, when said vanes are moved to closed positions asshown in full lines in the V Figure 3, an effectual closure will be hadwhereby to absolutely prevent the passage of any material quantity ofair from the annular chamber 2 through the discharge ports t into thefurnace combustion chamber. However, when said vanes are swung to thoseopen positions as shown in dotted lines in the Figure 3, under influenceof the operating ring 10 and the operating handle 12, the offset freeportions 17 will in no way detrimentally affect the discharge of airfrom the ports 4:.

Because of the mode of communication of the casing 1 with the airpreheating zone of an equipped furnace construction, it will beunderstood that a continuous and even in flow of preheated air will beeffected by way of the properly adjusted or regulated air register perse, into the combustion chamber of such furnace, this preheated air, ashereinbefore described, being evenly distributed about the annularchamber 2 of the register by reason of its mode of introductionthereinto both from the inlet opening 3 and from the lateral integralextremities 5 and 5'. By reason of this mode of air introduction intothe chamber 2 and through the ports thereof from the register per seinto the combustion chamber of the equipped furnace, it will likewise beunderstood that an intimate admixture of atomized oil and oxygen withinthe combustion chamber of the furnace will take place, thus, producing amaximum heating efficiency therefrom.

Manifestly, the construction shown is capable of considerablemodification, and such modification as is within the scope of my claims,I consider within the spirit of my invention.
